This I/O pack can interface up to two input-output Ethernet networks and a serial communications board. It provides up to 32 digital I/O points, 8 analog I/O points, and 2 analog outputs.

The pack has six individually configurable serial transceiver channels which can be used with RS485 half-duplex, RS232, and RS422 standards. The input needed to provide power to the PSCA pack is sent through a three-pin power input and dual RJ45 Ethernet connectors.

The IS220PSCAH1A pack has a Serial Modbus Master Service with a number of different features. These features are used for the six configurable ports on the PSCA pack. The configurations can be done at the port level. With the PSCA, the two Ethernet ports on the pack can be used to help support Ethernet Modbus Master Protocols; however, this configuration can only occur when being used on a simplex network.
